Title: Improvements in or relating to fuel element casings
Inventor: CRAIG HUGH ROBERT MORTON
IPC: G21C3/08
Filed: 1960-12-07
Abstract: 1,023,971. Fuel elements. RICHARD. SONS, WESTGARTH & CO. Ltd. March 7, 1962 [Dec. 7, 1960], No. 42156/60. Heading G6C. A fuel element is mounted within a channel in a gas-cooled nuclear reactor, means defining a Venturi passage located to one side of the channel axis being attached to or formed integral with either the fuel element casing or the channel wall. In the example described, a fuel element casing provided with external fins 10 formed in herringbone fashion and splitters 12 is housed in a reactor fuel channel which makes a close sliding fit with the outer edges of the splitters 12. To counteract the chattering of the casing within the channel when coolant flows, two of the splitters 12 are provided with curved flow guide surfaces 14 which define a Venturi passage located to one side of the axis 16 causing the coolant pressure to urge the casing against one side of its surrounding channel. The Venturi-defining surfaces 14 may extend along the external surface of the casing or be disposed at or near one end so that the Venturi passage lies between adjacent pairs of casings arranged end-to-end in the same channel. Alternatively, the Venturi-defining surfaces 14 may be provided on the channel wall.

Title: Cyclic redundancy check generator
IPC: H03M13/09
Filed: 1971-09-10
Abstract: 1345634 Check word generator INTERNATIONAL BUSINESS MACHINES CORP 10 Sept 1971 [1 Dec 1970] 42239/71 Heading G4A A cyclic redundancy check word generator comprises a matrix array of logic cells, and first, second and third input registers, the output of the matrix being connected to the second input register, the arrangement being such that in response to the presence in the first input register of a code polynomial, the generator progressively develops in the second input register a check word from successive bytes of a message word supplied to the third input register, the check word being the remainder produced by dividing the message word by the code polynomial. The generator may be used in conjunction with a number of devices supplying message words and a memory. The devices supply data words interleaved by byte, each byte having an associated memory address. The address is used to access from memory the code polynomial appropriate to the device from which the byte originated and the check word calculated in response to preceding bytes from that device. A new check word is calculated in response to the new byte and restored in the same memory location. The generator may be used to calculate a check word which is compared with a check word received with the data. Check word calculation: The check word calculator comprises a matrix array of cells each consisting of an AND and an exclusive -OR gate connected as shown, e.g. at 36 in row 2, column 2. The connections vary around the edges of the matrix due to the fact that the cells to which the feedback connections would normally be made do not exist, see for example the first row. The three input registers 30, 32, 34 store the division polynomial accessed from store, the previously calculated check word similarly accessed, and the new data character respectively all right justified and filled, if necessary, with zeros. Two arrangements for outputting data from the matrix are described. In the first, as illustrated, no connections between the output circuitry and components within the chain lines 150 are necessary, thus enabling the portion 150 to be conveniently made on a single integrated circuit chip. In this embodiment, depending on whether a 6 or 7 bit data byte is to be processed, rows 6 and 7 (i.e. the last two rows, the first being row 0), and row 7 respectively are disabled and prevented from modifying (apart from a one place shift in each row) the output of rows 5 and 6 respectively which are fed through to output AND gates which are connected to the last row of the matrix so as to compensate for the unwanted one place shift which occurs in each disabled row. For an 8-bit check word the whole matrix is used. In the second embodiment internal connections to the matrix are made, three sets of connections being made to the three last rows of the matrix via three sets of AND gates, one of which is enabled depending on whether a 6-, 7- or 8-bit data character is supplied.

Title: Facsimile System
IPC: H04N1/40
Filed: 1966-09-27
Abstract: 1,169,916. Synchronizing facsimile apparatus. XEROX CORP. 27 Sept., 1966 [1 Oct., 1965], No. 43082/66. Heading H2L. [Also in Division H4] In a facsimile system (see Division H4), facsimile signals derived in the transmitter by a document scanner are sent, together with scanning sync. pulses, over a telephone line to a remote receiver. At the receiver the separated sync. pulses (third waveform) are tested for coincidence with locally generated timing pulses (top waveform). An oscillator and frequency divider in the receiver generate driving pulses for a stepping motor which provides the scanning drive for the receiver printing stylus. If the sync. pulses do not lie within receiver-generated time gates (second waveform), the timing and driving pulse rates, and hence the scan rate, are increased to about 14% above normal. As soon as approximate synchronization is achieved (i.e. the sync. pulses fall within the time gates) the timing and driving pulse rates drop to about 3% above normal. When full synchronization is achieved, the pulse rates revert to normal. Failure of the receiver to become synchronized with the transmitter causes actuation of an alarm. Reference has been directed by the Comptroller to Specification 1,112,858.

A heat-sensitive material comprising a waterpermeable layer of hydrophobic thermoplastic polymeric particles dispersed in a hydrophobic binder and infrared absorbing particles in heatconductive relationship with the layer, the material becoming water impermeable or less waterpermeable on heating. The heat-sensitive layer may be self-supporting or coated on a support which may be coated with a water-permeable hydrophilic or hydrophobic layer. Carbon black and silver are specified as the infrared absorbers and polyethylene, polyvinylidene chloride, polystyrene, poly (methyl or ethyl) methacrylate, polyvinyl chloride, polyacrylonitrile and polyvinyl carbazole are the preferred hydrophobic polymers. The material may be exposed and developed as disclosed in the parent Specification. In the examples, a polymeric support is coated with a gelatine layer containing carbon black particles or colloidal silver and overcoated with a gelatine layer containing an aqueous dispersion of polyethylene or vinyl chloride/diethyl maleate copolymer particles, imagewise exposed to infrared and developed by (i) bleaching out the silver from the water-permeable areas or (ii) applying an aqueous dye solution to produce a dye master. Alternatively, the heat-sensitive layer may contain colloidal silver and sodium thiosulphate and is contacted with an exposed and developed silver halide emulsion to produce an infrared absorbent silver image in the heatsensitive layer by silver salt diffusion. The heat-sensitive material is uniformly heated to render it less water-permeable and less hydrophilic in the silver image areas and is then treated with an aqueous solution of gum arabic and carboxymethylcellulose to render the waterpermeable areas more hydrophilic and produce a planographic printing plate.
